Invest the time to learn how to fix this in software, you will not regret it. Better alternative to DS Posted by stoopkid in forum: Feb 6, 4. Have a flag a bit that controls this timer from the code outside the interrupt. How are you writing the code: Nov 23, 8, 6, I have a high-speed microcontroller application and I want to hook up a gpio pin on it to an output of a big delay external timer so that I don’t have to hold up the microcontroller cpu just to count a long delay.

This runs all the time. Feb 6, 1. I don’t want to use another microcontroller to make the timer itself. Both serial connections and USB to serial conversion connections are covered.

Feb 6, 6. Then, in the interrupt routine have a variable which is your virtual “timer” – you can have as many of these as you like as you like.

This is a nuisance for PCB development as this forms the letter H under the chip on the board which prevents wires from running through. Feb 6, 2. Jul 12, 4. Feb 6, 5.

Jan 6, 3, 1, When the register reaches zero – the time delay is complete and you stop decrementing. I also don’t want to leave the inputs floating as unpredictable results can happen.

The perfect approach for me is two monostable multivibrators, because one will be used for the pin and another to refresh the clock on an external flip-flop connected to the micro for other purposes. Apr 4, Yes, my password is:
